Missing exif tags from identify (6.6.9-7)

Post by cogocogo »

I'm having some issues where ImageMagick does not detect all EXIF data in some images.

First test is on a stock Ubuntu-12.04.3-LTS:

No EXIF tags are listed amongst the properties.

The last image contains a lot of EXIF tags in the properties.

The two images in question are:

https://raw.github.com/christeredvartse ... otated.jpg
https://raw.github.com/christeredvartse ... f-logo.jpg

Is this a known issue in the 6.6.9-7 version, or is there something wrong with the exif data in the 640x160_rotated.jpg image? The reason I'm using 6.6.9-7 is that I run some automated tests on Travis-CI (https://travis-ci.org), and they use the regular imagemagick package on Ubuntu-12.04.

Btw, when using the exif tool on both machines (not in the imagemageick package), all exif information is listed, so it seems that the images are somewhat correctly tagged.
